[Antennas] quad antenna height versus received signal

2002年4月16日 10:08:28 -0500

My antenna question involves quad antenna height versus received
signal. Here's the setup: my qth is in the W5 area in southeast Texas.
Antenna setup: five band gemquad, 20/17/15/12/10 meters, balun, one feed
line, tuner, transceiver -- center of antenna is at 34 feet high as per
instructions by gemquad. Optimal heights suggested are 34 feet and 64 feet.
I'm on a small city lot so 64 feet is not an option, also too close to
power lines behind house.
So basically, I have a gemquad at 34 feet, rotatable for short path, long
path or other desired path directions.
I'm curious as to how the received signal might improve having the quad at
a higher height. For instance, from my location, I have not yet been able
to hear any of the following countries, or if I have the signal was 2x2 or
maybe 3x3 but just barely -- YA, 9N, A5, S2, EP, 9M2 and XV. 3A is
another but that's because the mountains on Monaco block much of the
signals. I also don't hear the VU stations too well. The 9M and XV are
interesting because I have heard others louder in that area. My guess is
that maybe the 9M2 and XV stations I saw posted on the cluster were running
much lower power. I use the W6EL prop program and have been doing some
propagation and path studies. I haven't worked too many stations long path,
but find that an interesting phenonema. Also have heard some real echo-ey
US stations working dx pileups lately. If anyone's interested, the list of
all the dx countries I'm still trying to work is on my bio on www.qrz.com -
just look up my call sign. I've been trying to determine if a gemquad at
34 feet might be able to "work em all." If not, I might be able to visit a
club station in Texas or in another state, especially on the coasts, to get
a better shot at those that have tough propagation paths to my area. 
Anyway, I find all this interesting and again, I'm just curious about
height versus received signal, angle of signal and all that good stuff. Of
course, if you can't hear em, it's kinda hard to work even if you ran an 8
kw amp (hi hi) not that I would ever try that. Thanks. I'm interested to
see what others with quad antennas have found as far as received signals. I
never did get to set the gemquad for best front-to-back ratio but hope to
do so soon. I'm not sure if that will help the receive signal signficantly
but maybe it will help me gain a slight bit. Not sure, any advice will be
helpful.
